About The Position

Confiant is a cybersecurity company focused on protecting the advertising ecosystem. The Support Engineer is a hands-on, technical, customer-facing role that serves as the front line when malicious or disruptive advertisements affect publisher or platform partners. The role triages and resolves live incidents—including forced redirects, scareware, malware, scams, and policy-violating creatives—often under time pressure and with potential revenue or reputational consequences. Between incidents, the Support Engineer reviews reported creatives and makes blocking decisions, verifies and enables integrations, investigates discrepancies by tracing ad behavior across devices and environments, and shares findings with Product and Security teams. Success requires a strong technical foundation, investigative instincts, sound judgment during escalations, and a customer-first mindset. The position is fully remote.
